4 Claims. This invention relates to attachments for slicing machines and has more particular reference ably reduced, when providing a slicing machine which under pressing conditions can be made to operate automatically. j The object of the present invention is to provide a power driven mechanism which is adapted to operatively engage or disengage the reciprocatingobject holder of a slicing machine, so that the holder may either move automatically or be subject to hand operation.

A further object of the present invention is to provide suitable switching means for connecting r disconnecting the power drive attachment at any point'held by the reciprocating object holder to, at the samemoment, start or respectively stop the motor while operating said switching means. These and other objects and advantages will appear from the following description and the a pended claims.

In the drawings accompanying this specification one embodiment of the invention is illustrated, although it is understood that the same is merely for the purpose of affording a clear Luiderstanding of the underlying principle of this invention, so that those skilled in the art may Referring to the drawings and in particular to Figs. 1 and 2, th slicing machine support I0 comprises a frame made from a number of angular uprights I l, which are heldtogether by horizontally located pairs of angular iron bars, l2, l3, l4. I

This frame structure, which is preferably welded together, has secured to' the two angle.

irons I2 abase plate [5 for supporting an electric motor l6 which is adapted to drive a large sized pulley l1 secured to a shaft l8. The latter is rotatable in bearing blocks H] which are fast to the two angle irons l3.

An extended end portion of shaft I8 is provided with a bevelled pinion engaging a bevel gear 2 I, which is fast to a vertical shaft 22, rotatable in bearing blocks 23. These blocks are secured to horizontally located angles 24 which in turn are fast to the angle irons l4.

The upper end portion of shaft 22 is provided with a crank 25 operatively associated with a connecting rod 26 which is movably held to an oscillatable rod member 21. This member is shown connected to and may be integral with two slide f members 28, 29 movable on two respective horizontally held rods 33, 3| which are secured t two oppositely located iron angles 32. v i

The engageable or locking clutch member 23 is provided with a slot 33. Depending from the upper edge surfaces of thisslot are two progressively declining engaging surfaces 34, Figs. 1 and 5, adapted to provide a means for readilyengaging a clutch device 34', which isconnected to an readily understand it Without, however, limiting I the invention to the specific details shown therein.

arm 35 forming a part of a slicing machines conventional type object holder 35 (not shown in full).

This object holder or feed member 36 is slidable in part on a rod 37 held in the slicing machines frame 38. The latter is'seated against the inner wall surfaces of angles 39, which are secured to the top of and frame structure [0.

A horizontal end portion 43 of the vertical arm 35, Fig. 3, is provided with a threaded stud 4| form a part with the wherewith to engage a projection of a sleeve 42 slidable on a rail 43 secured to frame 38 and forming the second guide rodfor the object holder 36.

Clutch device 34 comprises a holder plate 44 which is clamped to the arm portion 40. A ver- .tical plunger housing 45 forming a part of said plate is provided with a closed top and has movable therein a spring-operated plunger 46 adapted toengage withits lower end portion, the slot 33 of clutch member 2 3. The :upper part of the plunger is provided with an extending connector pin 4'! movable in a vertical slot 48 of the plunger housing and forming a part with a control arm or bracket 49 movable with the plunger and guided by the holder plate 44.

' A control device 50, adapted to raise and to lower the plunger 46 by means of the bracket 49, comprises a control rod 5| throughout the length of the frame I!) and is rotatably held in and between the frame angles 39.

The end of the control rod extends beyond the length of the frame and its accompanying sheet metal casing 52, and has fastened thereto a suitable operating or switch handle 53.

To control rod 5| is fastened a lift element 54 of substantially the same length as the rod. It is located underneath the bracket 49, so that a rotary movement of the rod will raise this bracket and disengage the plunger from the clutch member 28.

A locking member 59 in form of a flat spring or any other suitable arrangement serves the purpose to maintain the plunger in the disengaged position illustrated in Fig. 4. y

In order to stop the motor from running while the clutch member 28 is in a disengaged condition, the control rod 5| has provided at one of its end portions an electric switch arm 56 adapted to operatively engage an encased electric switch 5'! of suitable design and of which its Wires 58 connect to the motor in a well known manner.

The mechanism shown and described provides therefore suitable mechanisms and switching means making it possible to either move the objectholder automatically or by hand.

It will be noted that the control handle may be operated to start the motor under any conditions and regardless of the object holders position relation to the clutch member 28. The inclined surfaces 34 will automatically raise the plunger dependent of the slicing machine, reciprocating means operated by said motor adapted to engage with the locking means; mechanism to hold the locking means in inoperative position; a switch for the motor and means for concurrently operating the switch with the locking means.
